IMPROVEMENT IN HEATING APPARATUS.

Specification forming part of Letters Patent No. 172.36% dated January18, 1876; application filled March 30, 1 875.

To all whom it may concern:

Be it known that I, D. W. ABBOTT, of Leetonia, in the county ofOolumbiana and State ot'Ohio, have invented certain new and usefulImprovements in Heating. Apparatus; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form part of this specification.

The nature of my invention consists in the arrangement of a fire-placeheater in the manner hereinafter set forth.

Figure 1 is a front elevation. Fig. 2 is a central vertical section online or a", Fig. 1; and Fig. 3 is a detail view of hot-air chamber J.

A represents ail-ordinary brick chimney, in which there is nofire-place. To adapt this chimney to receive my fire-grate two openings,a and b, are made in the front thereof. The opening a is near the floor,and provided with sliding doors B B, set in a metallic frame, attachedin any suitable manner to the front of the chimney. The opening I) is ata suitable height above the lower opening, and large enough to receivethe devices hereinafter described.

On the front of the chimney is secured a sheet or other metal frame, 0,provided with inclined vertical flanges l) D, extending from the floorupward for a suitable height, and connected with a hood, E, surroundingthe sides and top of the upper opening I), and projecting outward for asuitable distance, to prevent the smoke from getting out into the room.G is the basket-grate, attached to the chimney and to the side flanges DD above the opening a. Above the grate G is an inclined deflector, H, tothrow the heat forward into the room, and above said deflector is adamper, I, to diminish the space between it and the hood E. Back of thedeflector H, within the opening I) of the chimney, is formedahot-airchamber, J, which is to be made air-tight, and

provided with a pipe, d, for the admission of air into it, either fromthe outside of the house, from the cellar, or from the same room at ornear the floor. The air thus admitted into the air-chamber J becomesheated, andlis allowed to escape through a pipe, d, into another roomfor heating the same.

In connection with this fire-grate I use a metallic hearth, K, uponwhich the heater stands when there is no hearth in the room where theheater is to be applied. ()n-the hearth K is then placed an ash-pan, K,constructed to leave an air-space between it and the hearth, and asthere is an air-space below the hearth there is no danger of the floorunderneath catching tire.

The hot-air chamber J,with its pipes, maybe applied to ordinaryfire-grates in fire-places, if desired. i i

This heating apparatus may be applied to ordinary chimneys having nofire-places, and it may be used on new chimneys, without the necessityof building a recess in the chimney for the tire. I

By means of the damper above and doors below the grate all dust isavoided in stirring the fire, and the draft also regulated.

Having thus fully described my invention, what 1 claim as new, anddesire to secure by Letters Patent, is-

In a lire-place heater, the combination of the frame 0, with sideflanges D I) and hood E, the detlector H, hot-air chamber J, arrangedbehind the deflector, which forms the front thereof, the inlet andoutlet pipes 01 d, and

damper I, all constructed as and for the purposes described.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

DANIEL W. ABBOTT.
